IIRC this is due to prc-tools's startup code not initialising GCC's C++
exception handling code correctly.

IIRC the exception tables are currently placed in the global data. In
addition to the usual do-I-have-globals question, this means that even
on Palm OS devices with lots of memory any bloat is significant, because
global data is limited to 32K by a restrictive m68k addressing mode.

What is required is for someone who cares about C++ exceptions to look
at the prc-tools startup code. Sadly, whether I care about exceptions
or not, this is unlikely to reach the top of *my* list anytime soon, so
it requires someone else who cares.
